ABSTRACT:
A semiconductor laser performs high-speed modulation with a low-capacitance structure. The laser comprises a multilayered growth layer which is electrically isolated from a substrate and includes an active layer between a lower semiconductor layer of first conductivity type and an upper semiconductor layer of second conductivity type. A ridge is formed on the surface of the multilayer without reaching the active layer, and an insulating film is formed on the substrate main surface except for the ridge upper surface. An electrode contacts the second conductivity type semiconductor layer on the ridge upper surface and extends onto the insulating film beyond a second isolation trench, and an electrode which deviates from above the ridge is formed on the insulating film on a first isolation trench side and contacts the first conductivity type semiconductor layer located below the active layer.
